ARRANGEMENT OF CINEMAS IN MULTIPLEX CINEMAS
AND CINEMA ROOM FOR A MULTI-SCREEN CINEMA
FIELD
The invention relates generally to the field of multiplex cinemas, and in
particular, to
the arrangement of the cinemas and the cinema rooms.
BACKGROUND
Multiplex cinemas having several cinemas for projecting films are well known
today.
These multiplex cinemas are often installed in shopping malls or in specific
premises,
where suitable optimization of space is required. Multiplex cinemas in which
the
projection cinemas have a rectangular shape and are arranged forming
alignments of
contiguous cinemas are known, said cinemas having a projection screen at a
first
end of the cinema and stadium-type seating arranged on an inclined surface,
inclined
upwards towards a second end of the cinema. The rectangular shape of cinemas
is
adopted following the quadrangular distribution pattern of the posts of the
building;
this means that depending on the separation between posts, the projection
cinema
can have a smaller width, which limits the width of the screen and can even
call into
question the validity of the space for installing a multiplex cinema. Some
arrangements applicable to entertainment halls are known in the prior art. For
example, the utility model ES0246078U discloses a central area isolated by
means of
a peripheral partition of a series of individual chamber-type housings for
viewers.
Spanish patent ES0185779 discloses improvements to the arrangement of film
projection cinemas, combining a ramp that is lit up with indirect lighting
oriented
towards the exterior which frames the screen and replaces the usual black
framing
with an unnoticeable attachment of the walls of the cinema to the walls of the
ramp.
However, the proprietor of the present invention is unaware of the existence
of any
background document that allows satisfactorily solving the problems considered
in
reference to making optimal use of the space in multiplex cinemas and
maximizing
the width of projection screens.

Multi-screen cinemas are currently known, having a flat screen or a variable
curvature screen vertically arranged, on which frontal screen images are
projected by
means of film projectors located behind the projecting cinema room, higher
than the
tiers of seats. This arrangement of the film projectors brings about various
problems
among which the following may be cited:
the utilization of a part of the space aimed at the cinema room for building
behind the room the projection cabins and a corridor for its access;
a limited utilization of the light of the projection and visual deformation of
the
projected image on the screen due to the high location of the projector in
respect to
the screen and to the difference in the horizontal angle visualization in
respect to the
viewers, in function of their location within the cinema room;
in case of screens of large dimensions, the lack of capacity to offer
sufficient
luminosity forces frequently to the use of a simultaneous projection with two
projectors in each of the cinema rooms, with the assistance of mirrors or
prisms
which generate eventual convergence problems of the images on the screen.
The difference in the visualization angle and comfort for the viewer between
the first
and the last rows of the cinema room is well known by the users, who avoid the
occupation of the firsts rows or lower rows of seats in which they must adopt
an
uncomfortable position, having at the same time a worse vision of the images;
specially in small or medium sized cinema rooms. While it is true that
projection
rooms exist with characteristics oriented to obtain especial effects, as the
known
"OMNIMAXTm" cinema rooms, which use a screen with a surface similar to a an
spherical quadrant; the inventor does not know the existence of prior art
embodiments applicable to multi-screen cinemas having an arrangement similar
to
the present invention and solving satisfactorily the above related problems.

SUMMARY
The object of the present invention is an arrangement of projection cinemas in
multiplex cinemas, comprising: at least one first row of contiguous cinemas
provided
with a projection screen at a first end, with stadium-type seating for viewers
arranged
on an inclined surface, inclined upwards towards a second end of the cinema,
and
entrances to the mentioned cinemas. The arrangement of cinemas in multiplex
cinemas object of this invention comprises features which are aimed at
optimizing
space in a premise intended for a multiplex cinema for placement of the
projection
cinemas and maximizing screen size.
The arrangement of cinemas in multiplex cinemas object of this invention,
comprising
at least one first row of contiguous cinemas provided with a projection screen
at a
first end and with stadium-type seating arranged on an inclined surface,
inclined
upwards towards a second end of the cinema, in addition to entrances to said
cinemas, has constructive particularities aimed at solving the problems set
forth and
optimizing space and maximizing screen size such that all the cinemas have a
large
screen. To that end and according to the arrangement of the invention, the
multiplex
cinema comprises at least one first row of cinemas having a trapezoidal layout
with: a
larger end, a smaller end and two oblique sides. The cinemas of said first row
are
attached to one another by their sides and with their larger and smaller ends
oriented
in opposite directions with respect to said ends of the contiguous cinema or
cinemas.
The alternating orientation of the contiguous trapezoidal cinemas allows
maximizing
the dimensions of the larger end of the cinemas and placing a large screen
there, or
in any case a screen that is larger than one that may be used in a rectangular
cinema
having the same length and surface.
In this invention, the possibility of arranging below the inclined surface of
the cinemas
of the first row lower cinemas having a trapezoidal layout, having a smaller
surface
than those of the first row, has been envisaged, said lower cinemas also
having: a
smaller end, a larger end and two oblique sides. The lower cinemas are
arranged
- 3 -
CA 3057235 2019-09-30
with their smaller end oriented in the same direction as the smaller end of
the
cinemas of the mentioned first row. In this embodiment, the smaller end of the
lower
is vertically aligned with the smaller end of the cinemas of the first row,
making use of
the greater height of said smaller end of the lower cinema for placing the
corresponding screen.
A further object of this invention is a cinema room for a multi-screen cinema,
each
cinema room having a film projector, a projection screen and tiers of seats or
stands
with multiple rows of seats arranged to different heights. The arrangement of
the
invention has peculiarities in its construction concerning the location of the
film
projector and the arrangement of the screen, providing multiple advantages
concerning the management of the space intended for a multi-screen cinema,
improving the quality of the projection by minimizing the deformation of the
image
projected on the screen, providing a better utilization of the projector light
and
maintaining the format of the projection in which the movie has been created,
as well
as obtaining the same horizontal vision angle for all of the seats,
independently of the
position of the seats in the room and independently of the dimensions of the
room,
improving the visualization of the movie by the public.
The arrangement for a cinema room for a multi-screen cinema which is the
object of
the invention, having in each cinema room a projection screen, a film
projector and a
tiers of seats, has features aimed at solving the above problems of the
presently
known cinema rooms for multi-screen cinemas. For this purpose and according to
the
invention, a feature of the present arrangement for cinema rooms for a multi-
screen
cinema consists in that each of the projection rooms has a projection screen
with a
surface which adopts the form of a cylindrical sector with constant curvature,
being
said projection screen tilted towards the tiers of seats, forming said screen
an angle
with the vertical comprised between 5 and 10 , preferably 7 . With the
inclination of
the screen and its configuration in the form of a cylindrical sector, an
immersion
sensation is obtained by the viewers in respect to the scenes projected on the
screen
as well as a better aspect of the projections.

Another feature consists in the arrangement of the film projector inside of
each
cinema room, integrated in an intermediate area of the tiers of seats, and
oriented
towards the centre of the screen, forming with said screen an angle comprised
between 800 and 1000, the objective being an angle of 90 with absolute
perpendicularity in respect of the screen. This peculiarity permits the
integration in
the cinema room of the spaces usually located behind the room and aimed at
containing the projection cabins, so that a better utilization is obtained of
the space
for the parterre.
Said arrangement of the film projector, apart from preventing the deformation
of the
images, which occurs usually in the cinema rooms in which the film projector
is
arranged above the tiers of seats; permits a better utilization of the
projector light
given the perpendicularity of the projection in respect to the screen, being
unnecessary, in case of large surface screens, the simultaneous use of two
film
projectors and intermediate elements for re-directing towards the screen and
the
convergence on the screen of the images coming from the two film projectors
which
operate simultaneously. Furthermore, with this arrangement of the film
projector, the
light cast on the screen returns to the central area of the tiers of seats,
improving the
luminosity of the projection. With the arrangement of a unique film projector
in the
central or intermediate areas of each cinema room, it is possible to minimize
the
difference in vertical deformation among the different rows of seats, which
together
with the configuration of the screen in the form of a cylindrical sector,
provides an
optimized vision of the images by the viewers. Further, the inclination of the
screen
towards the tiers of seats or parterre provides the same angle for horizontal
vision
from all the seats, independently of the dimensions of the cinema room.
Additionally, and with the end to optimize the comfort of the users, at least
the first
row or seats or lower row of seats has bed-like seats, in which the viewers
can
arrange themselves lying or seating with a larger inclination than in the rest
of seats
of the rows of seats located behind, improving the comfort of the viewers.
